Why are my female guinea pigs fighting? How to stop dominance?

Updated On September 23rd, 2025

My guinea pigs are both female and 1 year old. They are twins. One of them dives at the other one and then the other will squeak high pitched what should I do. This is happening more and more each day. I have had them since they were 4 months old and they didn't do that at that age. The dominant one is the one diving at the other

Usually siblings raised together will be able to live together. It sounds as if you have one overly dominant female though. You can try keeping them in a larger cage with additional bowls, bottles, toys and hides. This may give them enough "elbow room" which may decrease the squabbling. If not, you may need to separate them for a few days. A gradual reintroduction can be tried, but if they continue to fight, permanent separation may be the only option.
